Letters Patent No. 113,349, dated April 4, 1871.

IMPRovEMEN-r iN AsHs|FTERs- .The Schedule referred to in these Letters Patent and making part of the same.

To all whom 'it may concern ,i

Be it known that I, GEORGE W. Roenes, of the city of New York, in the county and State of New York, have invented a new and improved Ash-Sifter and I do 4hereby declare that the following is a full,

clear, and exact description thereof', which will *enable*` others skilled in the art to make and use the same, reference being had to the accompanying 'drawing forming part of this specification.

Figure 1 represents a vertical longitudinal section of my improved ash-sifter.

Figure 2 is a transverse section of the same taken on the plane of the line a: x, iig. l.

Figure 3 is a detail siderview of the oscillating sieve.

Similar letters of reference indicate corresponding parts.

In my invention I bring together for the first time several things wellkn'own to the public, but never before combined to bring about'a useful result; and

t consists in the eombinationof the several parts,

ashereinafter described, to form an improved ashby a horizontal cross-piece, b. The lower piece b is` nearly or about in line with the bottom of the box A. The shaft B hasV th ns only two short axes .or pieces,

c\c,'on which it turns, and is .provided'with a handle, d, on one end, to receive oscillating motion thereby. The shaft B serves as a support for the sieve Cl. This sieve is made with straight sides, e e, each of which has a straight groove, f, in the middle, as shown in g. 3. The sieve is placed upon the-shaft so that the uprightparts of the latter iit into the grooves f, as indicatediu figs. 1 and 2. The sieve is thereby held irmly to the shaft, and' can be rocked `with the same. The bottom of the'sieve is perforated, as may also be the ends of the same, if desired.

gg are springs or rubber cushions, aiixe'd within 1 the box A, opposite the ends of the sieve. As the shaft is being oseillated it will also oscillate the sieve and cause the sanieto shake out the ashes into a box or vessel, D, upon which the box A is placed. The springs or cushions g q serve to gently arrest the sieve after each stroke, and to give it a shook to cause a rapid separation of the ashes. y

During the operation `the box A is closed by a cover, h. 'lhe sieve can at all times be withdrawn from the shaft B when it is to be emptied or cleaned.

Having thus described my invention, 4I claim as new and desire to secure by Letters Patentey The box A, having springs g g on its inner sides, the rook-shaft B, composed of part-s a a b 11 c c, and the sieve C, grooved in the middle thereof at ff, all combined as described to forman improved ash-sitter.
